Hi MARIO ALZAMORA,
Audio delay with Bluetooth headphones can be caused by the Bluetooth connection, drivers, or the specific app being used.
Please try these steps:
- Restart both the PC and the JBL headphones.
- Go to Settings > Bluetooth & devices > Devices, remove the JBL TUNE520BT, and then pair it again.
- Install any available Windows updates and update the Bluetooth and audio drivers through Device Manager or your PC manufacturer’s website.
- Run the Bluetooth troubleshooter in the Get Help app.
You can also follow Microsoft’s official guide here: Fix Bluetooth problems in Windows
Does the delay occur in every app or only in a particular app, such as a browser, media player, or game? Also, does the same issue occur when the headphones are connected to another device? While my initial response may not fully resolve the issue, I truly appreciate your cooperation as we work together toward identifying the most effective solution. Thank you so much for your understanding.
